Labour hire and traffic control sit at the higher-risk end of the WHS landscape. Workers are deployed to sites controlled by other parties, exposure to plant and traffic is constant, fatigue risk is elevated. This article covers what a WHS system actually needs to hold up in these industries, and where most systems fall short.
The compliance burden is significant, and the cost of getting it wrong, in both human and commercial terms, is high. This article is written from the perspective of someone who has built and maintained WHS systems in these industries, dealt with regulators, supported audits and embedded on site during high-pressure work.
Australian WHS law is harmonised across most jurisdictions through the model WHS Act. Key obligations for labour hire and traffic control businesses:
The starting point for any system is identifying which of these apply to your operation and at what depth. A multi-state labour hire business has more layered obligations than a single-state operation.
A WHS system that holds up under audit and, more importantly, actually protects workers needs the following components. Missing any of them is a gap worth fixing.
A documented WHS policy signed by the most senior person in the business, reviewed at defined intervals, and visible across the operation. The document itself is not the point. The visible commitment is. Workers can tell within minutes whether leadership genuinely cares about WHS or treats it as a paperwork exercise.
A documented process for identifying hazards, assessing risk, controlling risk and reviewing controls. The framework should match the model WHS hierarchy of controls (eliminate, substitute, engineer, administer, PPE) and be applied consistently. For labour hire specifically, the risk assessment must cover both the work being done and the host site environment. For traffic control specifically, the risk assessment must address traffic exposure, plant interaction, fatigue, environmental conditions and the public.
For high-risk construction work, a SWMS is legally required under the model WHS Regulations. Both SWMS and JSAs need to be specific to the actual work being done, not a generic template with site name swapped in. They must identify the actual hazards at the actual workplace, describe the actual controls being applied, be reviewed and signed by the workers performing the work, be available on site at the time the work is being done, and be updated when conditions change.
The most common audit finding in this area is generic SWMS that have not been adapted to the specific job. The second most common is SWMS signed without genuine review.
Every worker deployed to a site needs to understand the specific risks of that site, the controls in place, the emergency arrangements and the chain of command. Generic inductions are not sufficient. Site-specific inductions are required. Beyond induction, verification of competence is critical. The labour hire or traffic control business needs to know that the worker being deployed has the licences, tickets, training and demonstrated capability for the specific work.
Workers must be consulted on WHS matters that affect them. This includes hazard identification and risk control decisions, changes to work practices, and health and safety committee or representative arrangements. For labour hire, consultation with the host PCBU is also required. The labour hire business and the host PCBU each owe duties to the worker, and those duties need to be coordinated, not duplicated or dropped.
A clear, accessible process for reporting incidents and near misses, with timeframes, responsibilities and a defined investigation process. The process needs to capture incidents fast (within hours, not days), distinguish between notifiable incidents and other incidents, trigger immediate response for serious incidents, and drive systemic learning, not just blame. Notifiable incidents under the model WHS Act include death, serious injury or illness, and dangerous incidents. Failing to notify is itself an offence.
A documented training matrix for each role, with currency tracking. For labour hire and traffic control, this typically includes general construction induction (white card), industry-specific tickets, first aid certifications, site-specific inductions (refreshed on cycle) and internal training on fatigue, manual handling and mental health awareness. The system needs to flag expiring certifications before they expire, not after. A worker deployed with an expired ticket exposes both the worker and the business.
For traffic control particularly, but also for any operation involving overnight work, long shifts or significant travel, fatigue management is a specific obligation. A useful fatigue management approach includes a documented fatigue policy with clear thresholds, a fatigue risk assessment applied at scheduling (not after the fact), maximum shift length and minimum break requirements, travel time included in fatigue calculations, and escalation pathways when thresholds are breached. This is one of the areas most commonly under-developed in mid-size operations.
Records of equipment, inspection cycles, maintenance and operator competence. For traffic control: signs, lights, vehicle-mounted attenuators, support vehicles. For labour hire: any plant supplied by the labour hire business, with clear delineation of responsibility for plant supplied by the host.
Internal audit cycles, management review meetings and external audit (whether ISO 45001 or client-driven). Findings tracked through to genuine close-out, not paper close-out.
Auditors in this space have seen everything. The patterns that draw scrutiny:
The single highest-value question an auditor asks is: "show me how you closed the last similar finding, and how you have prevented it recurring." A system that can answer this question well is a system that is genuinely working.
In our experience, the most common gaps in labour hire and traffic control WHS systems are:
Build for execution, not for audit. A system that only exists to pass audit will fail at the workface, and the audit finding will catch up with you eventually. A system built to actually run the work will pass audit as a byproduct.
Get the senior leadership commitment in writing and visible. Workers and supervisors take their cues from what they see modelled, not from what is written in policies they have not read.
Invest in the training and competence layer. The single highest-leverage WHS investment in these industries is making sure every worker is genuinely competent for the work they are doing.
Treat the system as a living thing. Operations change, regulations change, lessons emerge from incidents. A system that is reviewed annually but not actively maintained will drift. A system that is genuinely lived will improve year on year.
